This is one of our state-of-the-art designs, a multi-purpose device for almost every application. This unit is composed of a pure tube pre-amplifier circuit of 6SL7x3 , with a built-in HPF input (high pass filter) and a solid-state 20Wrms non-feedback buffer amplifier, which can serve the following different configurations:
1. Pure class A single-ended tube pre-amplifier use 6SL7 x 3 ( alt: 6SN7/6SU7/6188/ECC32/ECC33/ECC35)
2. 20W/ch Class A hybrid power amplifier with 4-16 ohm driving capability
3. 20W/ch Class A hybrid high frequency band power amplifier for easy bi-amping (300Hz - 150Khz)
4. 20W/ch Class A hybrid headphone amplifier which can drive headphone with any sensitivity
5. 20W/ch Class A line level input integrated hybrid amplifier
6. Connect another power amplifier to form a bi-amping system
When using the HPF input mode, this amplifier can give the same loudness and dynamic level same as a 100Wrms power amplifier.
